SPECIFICATION forming part of Letters Patent No. 402,368, dated April 30, 1889. Application filed January 28, 1889. Serial No. 297,858. (No model.)

To aZZ whom it may concern: Be it known-that I, THOMAS WV. VARE, citizen of the United States, and aresident of Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Metallic An vil-Molds; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention and is a top view. Fig.

' 2'is a side view, a partof one section of the mold being broken away. Fig. 3 is an end View. Figs. 4, 5, 6, and 7 are details.

This invention has relation to metallic molds for casting faced anvils; and it consists in the novel construction and combination of parts as hereinafter set forth.

In the accompanying drawings, the letters A B designate the two lateral sections of the mold, which are made of metal, each section being recessedin its inner wall,'as at O, to provide one-half the matrix, as indicated in the drawings. V I

D D are channeled edge-seats in the ends of the sections, extending transversely, and adapted to receive the swinging bolts E, which are pivoted at a, and are provided with the nuts I). In separating the sections the nuts 12 are loosened, and the bolts swing outward from the channeled seats.

The anvil is designed to be cast base upward in the mold, and the main pouring-gate c is preferably arranged to enter the upper portion of the matrix at the base, and an auxiliary pouring-gate, d, is arranged to enter the matrix at the swell of the horn-plate, as indicatedat e.

F is a horizontal opening made by lateral notches or recesses in the rear of the mold-sections for the introduction of theface-plate piece into the matrix. Preferably this opening is at the rear end, as indicated, and its floor is levelwith the floor of the matrix.

G is a closing-gate adapted to close this opening and form a portion of the matrix thereat. The gate is pivoted to one of the mold-sections, as at g, and is provided with an extended arm or handle, h, which projects beyond the side wall of the opposite section, and is designed to be secured in position by a fastening, H, which is preferably ahook pivoted to the side of the section, as such a hook can be quickly operated. In the construction illustrated the closing-gate G is formed with an inwardly-proj ecting flange, k,beveled on its under side to form the under bevel of the rear of the anvil. Squared notches are made at l in the rear of the matrix portions of the molds, which, when said molds are locked together, form a square seat for the reception of the upper end of a core,-m.

I I indicate dowel-pins projecting from one section of the mold and entering sockets J in the other section. These dowel-pins guidethe sections so that their matrix-faces come together truly, and they facilitate the separation of the sections on parallel lines. The sections are provided with stout lugs f near the meeting edges, which are designed to afford purchase for a lever-bar when prying the mold-sections apart.

The face-plate piece Z consists of the main steel face-plate, K, and the horn-plate D, the latter being made of mild steelor wrought iron. These plates are connected by a neck, V, which extends from the inner portion of the main face-plate to the end portion of the horn-plate, which is above the level of said face-plate, as the piece lies in the bottom of the matrix-face down upon the floor thereof. The main face-plate K is of rectangular form, and is provided with the square opening 8 and with the round opening 15, said openings being made a little smaller than they are required to be in the anvil, the proper sizes being indicated by the core-pieces m and n, which are shouldered, as shown, to fit the openings 3 and t.

The horn-plate D is rounded and provided with the shoulder portion 1). The neck V of plate K is made narrow, so that channels a will be provided on each side of the same for the flow of the iron in the casting. The surlaterally into the matrix-chamber, and serving when the casting is made to strengthen the anvil at the joint of the horn and body portions. The horn-plate is also formed with a conical point, P, and a swell at S where the concave inner surface, r, commences. The auxiliary pouringgate terminates just inside this swell, and the molten metal reaching it first causes it to become thoroughly heated, so that it will be properly welded to the cast body portion.

The face-plate piece is inserted in position on the floor of the mold through the opening F, and the gate G is closed and secured. Before inserting the face-plate piece it is provided with the destructible cores m and n, which are inserted in openings 5 and t of the main face-plate, and when the face-plate piece is inserted the upper end of the core m enters the seat indicated at Z. The gate G closes against the inner shoulder, 10, of. the mold and forms the rear Wall of this seat. After the anvil is cast the apertures formed through the body portion by the cores mand n will be found to be larger than the openings s and tin the face-plate K, and these openings are broached out so that their inner margins will coincide with the Walls of said apertures.

Air-vents are provided at R R.

In using the mold the face-plate piece is heated before insertion into the matrix, and is placed there in heated condition to facilitate the welding, and the closing-gate is then driven to place, forcing the plate to its true posit-ion.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

1. A metallic anvil-mold consisting of lateral mold-sections and having an opening at the level of the floor of the matrix for the insertion of a face-plate piece, and a closinggate forming a part of the matrix, substantially as specified.

2. The combination, with the lateral sections of a metallic anvil-mold, notched or recessed to form an opening into the matrix at the level of its floor, of the fastenings holdin g the sections together, the dowel guidepins, and the closing-gate for said opening and its fastening, substantially as specified.

3. In a metal anvil-mold, the combination, with its lateral sections notched or recessed to form a horizontal opening into the matrix, and the closing-gate for said opening, of the face-plate piece adapted to be inserted through said opening into the matrix, substantially as specified.

at. In a metal anvil-mold, the combination, with the lateral sections of the mold notched or recessed to form a horizontal opening, and having the pouring-gates for the body and horn portions, as indicated, ot' the closinggate and the face-plate piece consisting of the main plate and horn-plate connected, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS \V. VARE.
